PHP file upload not working with dynamic path - php

Question

i am trying to write a php upload script to upload files to different folders. My code works for direct path (something like 'path/to/directory') but not for dynamic path taken from runtime.
$directory_self = dirname($_SERVER['PHP_SELF']);
$folder = $_POST['folder_name']; //final folder
$toupload = $_SERVER['DOCUMENT_ROOT'] . $directory_self .'/files'. $folder;
$uploadsDirectory = str_replace (" ", "", $toupload);
When i echo $uploadsDirectory it shows the exact path. Could any one help me what could be wrong in this?

Answer 1

You should check and see if the folder is created and if the script has permission to write files there.
What is the exact output of the upload script? (i.e. what errors does it throw?)

Answer 2

Try using dirname(__FILE__);
<?php
$directory_self = dirname(__FILE__);
$folder = "faruk"; //final folder
$toupload = $_SERVER['DOCUMENT_ROOT'] . $directory_self .'/files/'. $folder;
$uploadsDirectory = trim($toupload);
echo $uploadsDirectory."\n";
?>
Output on my laptop;
/home/test/Desktop/files/test

Try adding some debug stuff to see if the path you're generating actually exists and is writeable:
$directory_self = dirname($_SERVER['PHP_SELF']);
$folder = $_POST['folder_name']; //final folder
$uploaddir = $_SERVER['DOCUMENT_ROOT'] . $directory_self . '/files';
$uploadsDirectory = str_replace (" ", "", $uploaddir);
if (!is_dir($uploadDirectory)) {
die("$uploadDirectory is not a directory");
}
if (!is_writeable($uploadDirectory)) {
die("$uploaddir is not writeable");
}
$toupload = $uploadDirectory . $folder;
if (!is_writeable($toupload)) {
die("$toupload is not writeable");
}
